Definitions

  • the present invention relates to an electromagnetic actuator according to the preamble of the main claim.
  • a device is well known in the art and is often used to operate a (switching) valve, wherein generically the electromagnetically driven anchor unit with a valve spool or the like. Assembly of such a switching valve as an adjusting partner for exerting a force by means of the linear adjusting movement cooperates.
  • a concrete, known as vortexder known use case is the adjustment of the camshaft of an internal combustion engine.
  • the generic actuator as a pressure valve is located in the axial position to the engine camshaft.
  • the standing mounted adjusting device touches with an end face of the plunger unit which causes the camshaft adjustment valve.
  • the object of the present invention is therefore to improve a generic electromagnetic actuating device, in particular with regard to harmful frictional or transverse forces, which consists of a non-aligned or coaxial, but axially offset interaction of ram unit and control partner on an end face or engagement surface the ram unit act.
  • the plunger unit is provided with a cage-like holding portion in which a bearing or ball is rotatably inserted so that it can perform a rotational movement in the holding portion in response to the above-described friction or shear force on the ball and so a possible friction-related material removal significantly reduced.
  • the holding portion the end of the plunger unit, designed so that it integrally, so that formed from the material of the plunger unit and without additional component, acts so that on the one hand effectively an interior (as a receiving chamber for the ball) is limited or completed so that the ball can not fall out, but at the same time a predetermined portion for exerting its running and bearing effect from the cage-like holding portion can emerge, on the other hand within the receiving chamber, the conditions for a reliable, free and in the manner described Reib magnetic receiving rollers (rotational movement) are created.
  • an end-side edge portion of the receiving chamber by corresponding inward (ie directed radially in the direction of the center axis) flanging or folding to form a locking portion, wherein the corresponding wall portion in this embodiment of the invention and inserted run or Bearing ball is made by appropriate deforming tool insert. It is advantageous to set the (radial) measure of flanging, ie reducing the clear width in the transverse direction (and thus perpendicular to the linear adjusting movement of the plunger unit) to about 0.5% to 5% based on the diameter of the ball.
  • the internal width of the holding portion so a radial width of the receiving chamber for the running or ball bearing, with an excess or play relative to the ball diameter in such a way that on the one hand a reliable and Blockade-free rotation is possible in the desired manner, on the other unwanted transverse movements of the ball can be prevented. It is also ensured by appropriate depth design of the receiving chamber further education that the ball protrudes by an axial dimension of 10% to 30%, again based on a ball outside diameter, from the holding section for reliable force transmission to the control partner.
  • the present invention is particularly suitable for avoiding a manufacturing tolerance or temperature-related axial offset between ram unit and control partner with a resulting frictional effect
  • the present invention is not limited to this application and is suitable in principle for each application of a power transmission, which is exercised on the engagement side by a ram unit on a control partner.
  • the application "valve position" is also preferred, more preferably the adjustment of a camshaft or the like aggregate of an internal combustion engine, however, the field of application and the use of the present invention is not limited thereto.

  • Fig. 2 an enlarged detail view analogous to FIG. 1 with axially offset by a predetermined offset dimension control partner and 3 shows a detailed view of the end of the ram unit in front of the cage-like holding section with snapping inserted Laufg. Bearing ball.
  • Fig. 1 shows in the sectional side view of the basic structure and the periphery of the electromagnetic actuator according to a first preferred embodiment, mounted for camshaft adjustment by means of pressure on a valve slide 10 shown only schematically and cut a (not shown) switching valve unit for the camshaft adjustment of an internal combustion engine.
  • a plunger unit 12 which is part of an anchor unit of the electromagnetic actuator shown, and together with a cup-shaped anchor portion 14 within a two-part housing consisting of a housing shell 16 and a housing bottom 18 movably guided anchor unit is formed. More precisely, this armature unit 12, 14 is enclosed to form a magnetic circuit of a yoke core unit 22 formed integrally with an intermediate, conically tapered middle section 20 in the present embodiment, which forms an outlet opening for the tappet unit 12 at the front end and a hollow cylindrical tappet guide 24 in this area offers, which encloses the ram unit on the shell side over a predetermined axial length section.
  • the yoke core unit 22 is in turn radially surrounded by a coil unit, which is formed from a coil holder 26 which carries a winding 28 in an otherwise known manner.
  • the energization of this winding then causes the electromagnetic field of the winding drives the armature unit 12, 14 and thus the plunger in the plane of the figure in the axial direction left out of the yoke core section 22, while exerting a movement-inducing force on the valve slide unit 10.
  • the coil holder 26 is sealed via ring seals 32, 34 with respect to the housing elements 16, 18.
  • Fig. 3 illustrates in the detailed view of the engagement side design of the plunger unit with a cage-like holding portion in which a bearing or ball bearing 36 is rotatably mounted. More precisely, the arrangement of Fig. 1, Fig. 3 at the end a hollow cylindrical recess 38 in the ram unit as a receiving chamber for the ball 36, this by means of a at the outer end of the ram unit (or a wall of the receiving chamber 38) in the form of a inwardly directed to the longitudinal or movement axis undercut 40 is held. By appropriate design of this undercut - as shown in Fig.
  • this has a radial extent b, corresponding to 0.1 mm at a typical ball diameter d of 4 mm - the ball 36 can be reliably held freely rotatable in the chamber 38 ,
  • the insertion of the ball 36 by simply clipping causes.
  • the chamber 38 is radially dimensioned so that a radial clearance s between a ball outer wall and a radial ball inner wall sufficient rotation in accordance with the invention allows, with additional lubricant support this.
  • Actuators to co-operating control partners in particular switching valves or the like. Achieved, in which, due to production or temperature-related tolerances, not always coaxial interaction can be achieved, but an axial offset must be taken in the direction perpendicular to the direction of adjustment.
